or sfr. LOUIS, MISSOURI RDTARY MOTOR.

To all lwlwm it may concern Beit known that I, JOHN Coornn Perm, a. citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have inventede new and useful Improvement in Rotary Motors, of which the following is a specification.

.This invention relates to motors and more particularly to rotary motors or engines It has for its principalV objects to secure the full force and benefit ofthe motive agent or fluid, whether it be steam, water or other fluids or liquids under pressure, or the products or force of e. combustion or n hydrocarbon or ot-her explosive; to utilize the friction of the agent. or fluid upon the surface of a movable motor element as disreaction as a fullyappear.

It is knowxrthat the passage of any fluid,

. liquid or gas under pressure through a pipe,

tube orv passageway 1s. impeded by friction.

. This friction. 1sv generated` und1 exists materially. and effectively only invclose proximity tothe vwall or walls oZ the passageway. or example, in. a.y passageway' whosel walls are aconsiderabledistancofapart; thereis a centralfliody Yof theiiuicr or other agent which is o'utof therengeV of effective friction so thatil: passesfreely without appreciable resistance. The present invention, therefore, contemplatesy thefconcentration of friction by passingthe fluid or other agent through a restricted or shallow but relatively wide passageway havinge relatively large wall surface and. movablein theA direction of the flow or travel osueh'agent.

The invention consistslin the parts and in the arrangements and combinations of described-and-elaimcd. It,

parts hereinafter is tobe understood, however, that I ,do not limit myself to the specific structure shown,

motive agent or fluid nor to any particular' by the term steam.4 which will hereinafter be generallyused; throughout the specic/ tion and claims.

elements; Fig. 4 is a similar view of the companion element; and Fig. 5 is a. fragmentary view of the division plate.

The motor or concentrator shown in- Figs. 1 to 5 of the drawing illustrates an adapta tion of my invention. It comprises a ri# zontal shaft/1 which is journaled in standards 2. Fixed on the shaft to move therewith is a rotor or revolving power element 3. As shown, this element comprises two members 3 and 3" which are secured together by bolts 4. These members 3 and 3 are exact duplicates.- They are substantially cylindrical and have peripheral flanges 5 at' their inner margins which are perlo'rated toY receive the securing bolts 4. Each of the but narrow channel or groove 6 w is arranged spirally. The outer end @ofthe groove terminates near the-periphey member, while the inner end is a widened, as at 6", and opens into the 'centrali bore 7 in which the shaft 1 is tightly fitted; The members 3 and' 3* arev placed face"v to face with e division p shown in Fig. 1.. The rotor isv thus vided with two oppositely segeways which" are very shallowA orV narrow between their convolute walls, butirclatively wide transversely. 'The outer terminal por tions of the spirals 6 are made'to'overlp lishedbetween them through a slt=9insad division plate 8.. The shaftl 1 lsprovdfed' with two axial chambers 10 whiclrcommuni; cate respectively with the inner ends ofthe spirals 6 throu h openin il'. 4The: outer end portions o -the cham rs lo'commun c-ate with annular chambers. 12 in 'thc'stand adsl2 through' openings 13. The respective chambers-12 communicate witha steam -at'xpaplypipe i4 through -valves 17 and 18 areprovided'in the respec tive branches. An exhaust pipe 19 conbsageways starting froml a centralor axis of its longest convolutions adjacentto the members is provided with arelatively..l

periphery of the rotor and then returning to axis thereof, there is a powerful .concentration of friction upon the walls of the passageways at points remote from the axis and reiictioii is entirely eliminated.

In some cases a heater 24 may be placed under or adjacent to the rotor so as to reheat or superheat the steam passing through the restricted passagewuys.

By making the rotor in two sections as shown, the sections may be cast or made as exact duplicates and bolted together with the interposed division plate to constitute the two passageways. Of course, while the two sections are alike when detached, their spirals are the reverse of each other when the sections are placed together.

To operate the motor-steam is admitted into one of the chambers 12 whence it passes into the axial chamber 10. It then passes through the opening 11, through the spiral passa way at that side of the rotor to the perip eral portion thereof, and thence throu h the opening 9 in the division plate into tie opposite spiral passageway and is exhausted out through tliewopplosite'.faxialA aast.

The direction of rotation is controlled by o exiing and closing the respectivefvalvesl 'or 18 and Q9. or 23, as the case maybe. y

Obviousl a plurality of-the rotors may be mounte on a sin le shaft; and the rotor or rotorsimay each ave a plurality of=vthe spiral passageways.'So,l too,l 'instead of making the rotor-as a castini or solid body, annular chambers' or manifo ds may be arg ranged on thefsliaft in communication VAwith the 'axial chambers therein anda flattened Y pipe or tube or a fp lurality thereofrr'iafyfvbeI coiled about` the axis' ofthe shft'in the off'a lhelx and havetheir endsconnectedto the' respective annular-chambers@ or mani-v folds.
